Is it a function or not a function

BigorU [14]

Answer:

This is NOT a function. Because if you used the vertical line test it would hit that line 2 times.

Point M is the midpoint of segment QR. If QM = 16 + x and MR = 2(x + 2), find the length of QM.

pav-90 [236]

Just add them
QM+MR=QR
16+x+2(x+2)=QR
16+x+2x+4=QR
20+3x=QR

The diameter of a circle is 6 m. Find its area in terms of pi

Pie

<h2>Answer:</h2><h2>9 pi m^2</h2>

Solution,

Diameter=6 m

Radius= 6/2=3m

Area of circle= pi r ^2

 = pi *(3)^2

 = pi*9

 =9 pi metre^2

Hope it helps

Good luck on your assignment

What is the value of y? Enter your answer, as an exact value, in the box.

Amanda [17]

So for the 40-40-90 degree triangle, whenever the two legs are x values, then the hypotenuse is x value times the square root of 2.

--> a changed into a√2
√2 changed in √2 * √2
= 2

So the hypotenuse of the 40-40-90 degree triangle is 2.

Now for the 30-60-90 degree triangle, the smallest leg with the value of x is then changed to the value of x√3 if finding the longer leg.

-> a is changed to a√3
2 is changed into 2√3

So, y is 2√3 or approximately 3.46 units.
